Through construction and development for about 3 years, WISCO on-line website has become a quite large scale, and is the best comprehensive special website in Qingshan District, and one of the few successful networks content service supply model in the special networks in China, of which, VOD video order program is the No. 1 service.

VOD flow media digital web video service system being successfully reconstructed in 2005, under conditions of not reconstructing the network line, aiming at the space bottleneck, line loss and bad carrying capacity and others of the former VOD system, we have realized the following by applying a large number of software programming:

The quarter source shunt, IP shunt, service equipment performance shunt, single-machine multi-port balance, magnanimity load delayed storage these 5 kinds of control mechanisms, many kinds of shunts and servers balance have been done for the order program request of the user;

At the same time, the system structure has adopted distributed structure, utilizing the equipment location distributed type placing, content provision in layers and data distributing type transmission;

As for the security, the sole created multi- plug-in unit can realize the verification for the user identity, theft-resistant to the quarter source and download resistant, and fully protecting the program resources. At the same time, server fire-proof configuration and distributing type system can weaken and isolate external impact layer by layer, thus ensuring the security of the server;

The system is free for the content service of Internet, and enhances to high-level and professional content service level and increases its expansibility, repeatability and newly increasing capacity, can realize one time reconstruction and provide good service permanently, enabling the expansion space in the future to be easier. We have fully realized 100% self-development and technical innovation, in the software development on shunt and theft-proof, we are at the front for the network video order program sector. It’s used in all 8000 WISCO wide band network users covered by WISCO wide band scope, provides simultaneous on-line service capacity for 2000 personnel, can reach the program flow of 550kbps, for bringing smooth and clear video enjoyment for users.

During “World Cup”, it can provide high-quality live video and recording of actual contest; It shall enable WISCO wide band users to enjoy the exciting video and audio recreation just at home.
